New GPU for my build.

Hello everyone.

I have recently finished building my 'gaming' PC but with a few components taken from my old rig.

Specs currently
GPU : Nvidia GeForce GT240 1GB ( old PC )
CPU : Intel Pentium G2030 3.0GHz Dual Core
RAM : 2x4GB Corsair RAM
MOBO : Asrock H61M MicroATX
HDD : 500GB 5400rpm Seagate ( old PC )
PSU : 500W 80+ Bronze
OS : Windows 7 Enterprise 64bit
Screen : 1280x1024 VGA monitor ( ancient )

I have decided on a new GPU to buy. The Nvidia GeForce GTX 750ti as the power consumption is fairly low, and have heard decent reviews about it. My question is should I get a 1GB version or a 2GB version? The price difference is fairly minimal, but I would like to know what the 2GB version could do better?

I do not plan on using SLI anytime in the next few years ( I dont even think the GPU can support it any rate ) but would my monitor affect the quality of the image displayed? And would the GTX 750ti be able to play games such as Skyrim, Arma 3 and Witcher 2 on High graphics? My current GPU gives me around 34 FPS on low in Arma 3 which is someone disappointing.

Many thanks

    Get the GTX 750 Ti 2GB.

    A lot of games use well over 1GB of VRAM for various reasons (large textures, AA, backbuffering, high resolutions). Basically at higher resolutions more textures are loaded and in order to keep all these textures/high settings/AA to run smoothly you need more VRAM. If you don't have enough VRAM you have to turns things like AA down in order for the game to run smoothly. Like with RAM, more you have, more smoothly multiple programs will run at the same time. With more VRAM, more textures and detailed can be loaded and run smoothly.

    The VGA port that you use doesn't make a bit of difference especially at that resolution. It can affect picture quality to some degree, but it's likely you won't notice.

    And yes 750 Ti doesn't supports SLI.

    You'll be able to max out the listed games at your current monitor's resolution and get ~60 fps
